KASIER SEIFRIED, OF MAMARONEOK, NEW YORK.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 326,680, dated September 22, 1885.

Application filed July 28, 1885.

To all whom it may concern.-

Be it known that I, KASPER SEIFRIED, residing at Mamaroneck, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

My said invention relates to that class of devices known as 1nonkey-wrenches; and it consists of certain improvements whereby the sliding jaw may be released by a slight movement of the handle, which is pivoted to and embraces the lower end or shank of the stationaryjaw, and also embraces and is adapted to engage with notches on the shank of the sliding jaw, as will presently be more fully described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a perspective view of a wrench embodying my said invention; Fig. 2, a longitudinal section of the same, and Fig. 3 a transverse sectional view looking to the right from the dotted line 3 3 In said drawings, the portion marked A represents the main jaw of the wrench; B, the sliding jaw, and C the handle. The main jaw A has a shank, A, on which the sliding jaw is mounted, and preferably has scale-marks on its side for conveniencein setting said sliding jaw to position. It has a pivot-hole in its end, by which the handle is secured thereto. The sliding jaw B is mounted on the shank A of the permanent jaw, and is adapted to be moved thereon as desired. It has a shank, B, which lies alongside the shank A, and has serrations b in its outer face. The handle 0 is secured to the shank A by the pivot a, and has a hollow portion, G, which surrounds the shanks A and B, and upon the inner face of this hollow portion are serrations 0, corresponding to the serrations b in the shank B. There is also secured to this handle on the back side a spring, G, which extends out over the shank A, and operates to hold the serrations 0 into engagement with the serrations 1), except when forcibly separated therefrom. Small projec- (No model.)

tions 0 are preferably formed on the end of this spring, and extend down on each side of the shank A.

The method of using my improved wrench is as follows: When it is desired to adjust the wrench, the handle 0 is forced back slightly, bending the spring 0 and disengaging the serrated portions of said handle and the shank B. The jaw B can then be moved along the shank A of the jaw A until it reaches the desired position. The handle is then released, and the spring (3 forces it back into line with the shank A, and brings the serrations again into engagement. By this means a very convenient and speedy adjustment of the wrench may be made, and the parts,when in operative position, remain in the ordinary and wellknown relation.

The force employed in using the wrench holds the working parts into firm contact, as will be readily understood.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a wrench, of a permanent jaw having a shank, a sliding jaw mounted thereon and having a serrated shank arranged alongside the shank ofthe permanent jaw, a handle pivoted to the shank of the permanent jaw, and having a hollow portion surrounding both it and the shank of the sliding jaw,with serrations therein corresponding to the serrations on the shank of said sliding 2. The combination of the jaw A, having shank A, the sliding jaw B, having shank B, with serrations therein, the handle 0, having hollow and internally-serrated portion 0, surrounding the shanks A and B, and the spring 0 substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

KASPER SEIFRIED.
